NLRG was formed in 1957 to help in the study of birds in the Lancaster and District Birdwatching Society area. There are currently 12 active ringers. Species currently being studied include: Pied Flycatcher, Bearded Tit, Sand Martin, Twite, Goosander, Oystercatcher and Grey Wagtail. Migration has been studied for 28 years at Heysham. We welcome anyone who wants to observe, help or perhaps wish to become a ringer. Photo: A Heysham-ringed Twite on the Mull of Kintyre (thanks to Eddie Maguire)

Good Productivity by Resident Species

It certainly looks as though most of our resident species have had a good breeding season. To date we have made four post breeding season visits to Jerry and Barbara's woodland edge garden and caught 375 different birds. This compares with last seasons 13 visits between August and April when we handled 571 individuals. We are using the same 100 foot of mist nets throughout

So far this season we have caught 90 Great Tits compared to 85 in the whole of last season. Bullfinch at 25 compared to just 21 last season and we have already caught 22 Great Spotted Woodpeckers the same as last season. Blue Tits totaled 153 last season but already this season we have caught 133. Most other species have done really well the one exception is Coal Tit with only 16 so far this season compared to 115 last season in total. Few Coal Tits breed locally and we usually get an influx from breeding areas further north later in the season.

Good productivity is shown by the high numbers of juveniles in the catch. Blue Tits are typical 91% were juveniles compared to 63% last season after poor productivity.
